From 427120681a547c6891f5e458abab298ea7fea472 Mon Sep 17 00:00:00 2001 From: Tejas Bhumkar Date: Thu, 21 Mar 2024 14:22:20 +0530 Subject: [PATCH] arm64: zynqmp: Disable Tri-state for SDIO Since the zynqmp pinctrl driver now includes support for the tri-state registers, ensure that the pins needing output-enable are correctly configured for SOMs. Currently, there is an issue with the detection of the MMC for the SOM kv260, resulting in the following error: ZynqMP> mmc dev 1 Card did not respond to voltage select! : -110 To address this problem, configure the SDIO pins for output-enable to enable MMC detection.
